Alpha Image Texture


The Alpha image texture utilizes an image's native alpha channel to provide transparency. This image type accepts PNG, TIF, and .EXRAlso known as OpenEXR. This image file format was developed by Industrial Light & Magic and provides a High Dynamic Range image capable of storing deep image data on a frame-by-frame basis. files.

Alpha Image Parameters


Controls the image brightness. Lowering the value causes the image to appear darker on the surface.


Color Space

Determines the color space of the image texture.


Legacy GammaThe function or attribute used to code or decode luminance for common displays. The computer graphics industry has set a standard gamma setting of 2.2 making it the most common default for 3D modelling and rendering applications.

Controls the image's luminance and can tune or color-correct the image but can only be used with the Linear sRGB+Legacy Gamma color space.



Inverts the image's color output values.


Linear sRGB Invert

This option is used to swap the order of gamma correction and image color conversion.


Border Mode

Sets the behavior of the space around the image if the image does not cover the entire geometry. The default behavior is Wraparound, which repeats the image in the areas outside of the image's coverage. If you set this to white or black, the area outside the image turns white or black, respectively.



The file path name of the image texture.



Should be activated if the file needs a reload or the preference of the image file has been changed.


Image Chosen Layer Name

Indicates the chosen layer name, if the current image has multiple layers.


IESAn IES light is the lighting information representing the real-world lighting values for specific light fixtures. For more information, visit Photometry Mode

Can be used to adjust the normalization of data from an IES file.
